Multiple Choice

Air spirals in a low-pressure system in the Northern Hemisphere _______ and in a ________ direction.

• upward, clockwise

• downward, clockwise

• upward, counterclockwise

• downward, counterclockwise

Multiple Choice

A low-pressure system forms when ______ from Earth's surface.

• warm and moist air rises

• cold and dry air sinks

• cold and moist air sinks

• cold and dry air rises

Pressure Systems

Low-pressure system - clouds form - associated with rain or snow

-blizzards, storms

High-pressure system - clouds do NOT form - mild weather

-droughts

The steps in which a thunderstorm forms

• 1. Air is forced upward rapidly, it cools, condenses, and forms tall vertical clouds.

• 2. Water droplet and ice crystals begin to fall.

• 3. As they fall, the combine and become larger.

• 4. Heavy rainfall cools the surrounding air.

• 5. The cool air sinks and the warm air rises to take its place.

• 6. The resulting convection currents produce strong winds.
